Which of the following are common types of limited-energy cabling used in installations?

The selection of Category 5e, Category 6, and twisted pair cables as common types of limited-energy cabling is correct because these cables are specifically designed to support low-voltage data communication within various installations.

Limited-energy cabling typically refers to cables that carry low-voltage power or data signals, which is essential for safe operation in environments where higher voltages could pose a risk. Category 5e and Category 6 cables are types of twisted pair cables that are widely used for network connections, including internet and telephone services. Their construction allows them to handle higher data rates and minimizes interference, making them ideal for limited-energy applications such as structured cabling systems in commercial buildings.

In contrast to the selected answer, while fiber optic cables and coaxial cables do serve specific purposes in telecommunications, they are generally not classified as limited-energy cabling in the same context as the twisted pair options. Fiber optic cables, for instance, are primarily designed for high-speed data transmission over long distances and require different handling than typical limited-energy cabling. Similarly, non-shielded twisted pair cables and data cables may not sufficiently encompass the broader classifications or applications of limited-energy cabling, and single-core and multi-core cables are typically associated with more specific uses
